Simple question I hope....
How do I send data to and from an ASP.Net (server side) web page to a
ActiveX Control (client side) embedded in a web browser???
What I need to do, is I have image data (mostly TIFF format) that need to be
sent to our custom Image Viewer (ActiveX control). So far I can get the
TIFF image data loaded into a Byte Array in C# on my ASP.Net web page, But
how do I send this data now to my ActiveX control on the client side? The
ActiveX control is written in VC++ .Net 2003 using MFC so its unmanaged.
Also I need to do the reverse too, I need to be able to send Image data from
the ActiveX control back to the ASP.Net web page.
Thanks,

How the client-side ActiveX Control gets it's image data depends on how the
client-side ActiveX Control was developed to work. Generally, this sort of
client-side component fetches its own data from a server in some way, but I
couldn't tell you specifically in this case.

Right now the ActiveX Control has a method to load an image from a memory
pointer:
BOOL CCDMS_ViewerCtr l::LoadDocument (CLeadBitmap * ltbm);
The actual data from the server side is being sent as a LeadTools Bitmap.
At least this is how its written now.. But I can rewrite the control to work
anyway I need it to work.
If I'm understanding you right, The ActiveX Control itself is going to have
to send a request to the web server for the data? Would this have to be a
WebService?

no, you can use any protocol you want. the simplest would just a HTTP GET of
the image. to upload just do a HTTP POST of base64encode of the image. see
the wininet api for using the http protocol from your active/x control.

Hi,
Our team have a web project which includes some C# ActiveX DLLs.
On some developers' PCs, the code which calls methods in the ActiveX
dll is succesful - no exceptions. On other PCs, the ActiveX control
doesn't even seem to get loaded. (On the failing machines, if we try
and debug down to where the ActiveX DLL method is invoked, both Visual
Studio
and IE hang.)
